commit 2a60333bac6c807055d7d87aa9eaff5ffd18e587

fix two typos

Turns out my times were measured in centiseconds rather than milliseconds
as advertised. Oops.

Only discovered when looking to make them exact for the first time. Had
mostly ignored the values as "probably way off anyway". That appears to
have been an accurate assessment. X)

It does show nicely how the algorithm doesn't care about absolute values.
It operated just fine on centiseconds.
